I have a 2000 concorde with a 3.2 and the car died out on my wife one night and and the oil light went on. Now every time you start the car and raise the rpm the engine sounds like it has no oil. I just changed the oil two weeks before this happened and now the oil looks real black. can anyone give some advice please. i was thinking the oil pump went out but then someone told me it could be some seal in the back. any help would be appreciated.
